Mining Equipment: A-Z List for Maintenance Contractors
A highwall mining system is typically used for surface mining. It consists of a remotely controlled continuous miner to extract coal from exposed seams by driving a cutter module into a coal seam under a high wall. The coal is mined by the action of the cutterhead that is raised and lowered to dig out the entire height of the coal seam.
